MED12-related syndromes

Disorders

FG syndrome (Opitz-Kaveggia syndrome), Lujan-Fryns syndrome

Gene Name

MED12

Clinical info

Mutations in the MED12 gene have been found in individuals with clinical diagnoses of FG syndrome (Opitz-Kaveggia syndrome) and Lujan-Fryns syndrome. The gene is localized to Xq13. The majority of mutations have been found in a select number of exons (4,5,20,21,22,28 and 36).

Indications

Molecular testing is useful to confirm the diagnosis and to identify the disease causing mutations within a family to allow for carrier testing and prenatal diagnosis.

The specimen should be kept at room temperature and delivered via overnight shipping. FedEx is preferred. If shipment is delayed by one or two days, the specimen should be refrigerated and shipped at room temperature. Do not freeze the specimen. Samples collected on Friday can be safely designated for Monday delivery.

Turnaround time

6 weeks

Prenatal testing

Prenatal diagnosis is available if the familial mutation is known. Additional fees for cell culture and maternal cell contamination may apply. Maternal cell contamination studies are required for all prenatal molecular tests. Contact the laboratory prior to sending a prenatal specimen.
